Monitoring Airport Service Quality: A Complementary Approach To Measure Perceived Service Quality Using Online Reviews, Kiljae Lee, Chunyan Yu
Monitoring Airport Service Quality: A Complementary Approach To Measure Perceived Service Quality Using Online Reviews, Kiljae Lee, Chunyan Yu

Based on 42,063 airport reviews collected from Google Maps, we conducted a sentiment analysis and a topic modeling. We showed that the sentiment scores computed from textual reviews are good estimates of their paired star-ratings (r=0.63, p<0.01). Next, using the LDA (Latent Dirichlet Allocation), we extracted latent topics from the textual reviews and compared them with the standard categories utilized in the Airport Service Quality survey (ASQ). The topics extracted from reviews correspond well with the categories used in ASQ. We, in turn, compared the online ratings with the ratings annually updated by ASQ. While online reviews discuss almost identical topics with those of ASQ, the correlation between the ratings from two was weak (r=0.2). We suggest that the text mining approach using online reviews not only provides an inexpensive, dynamic, and locally customizable means of monitoring airport quality but also complements the standard survey by offering an alternative metric. ><0.01).

The 18th Air Transport Research Society World Conference (ATRS) was held in Bordeaux, France, from July 17 to July 20, 2014. The conference attracted some 347 participants, and 321 papers were presented. The guest editors have selected six papers to be included in this special issue. These papers cover a wide range of topics presented and discussed at the conference and offer important contribution to the literature on air transport.

A Taxonomy Framework For Maritime Cybersecurity: A Demonstration Using The Automatic Identification System, G. C. Kessler, J. P. Craiger, J. C. Haass
J. Philip Craiger, Ph.D.
The maritime transportation system is increasingly a target of cyber attacks. This paper describes a taxonomy that supports the creation of adversarial cyber models, risk mitigation, and resiliency plans as applied to the maritime industry, using the Automatic Identification System as a specific illustration of the approach. This method has already been applied to the aviation sector; retooling it for a maritime example demonstrates its broad applicability to the transportation sector, in general.
